Working Principles

The ENC28J60T-I/SO is an Ethernet controller that enables communication between an embedded system and an Ethernet network. It operates by receiving and transmitting Ethernet frames using the integrated MAC and PHY. The SPI interface facilitates communication with the host microcontroller, allowing control and data exchange.

When a frame is received, the ENC28J60T-I/SO performs CRC (Cyclic Redundancy Check) verification and error checking. If the frame is error-free, it can be processed by the host microcontroller. In case of transmission, the controller handles collision detection and automatic retransmission.
